SAFETY-RAZOR.

' v4exact description ot the invention, such as this specification. 15

Willenable others skilled in the art to which it appertains to Amake and use the same, reference being had tothe. accompanying drawings, and to the letters and iigures of reference marked thereon, which `:form a part vof ly invention relates to 'improvements in safety razors.

My improvements relate more particularly to the adjustment of the guard members oi' a razorl of the class setforthfin my previous patents'numbered 835077 and`856172', and dated Nov. 6th, 1906 and June 4th, 1907, res ectively.

n my improved construction' two yua'rd members are employed, both, however, eing connected with a single stem which is slotted in line with the division between the two' members. is threaded the ou ter The outer extremity" of this stem to engage a riut swiveled within ortion of the handle, the nut being rovi ed with a protruding member whic extends beyond the outer extremity of the handle and engages the same. By operating this rotary nut member, the two-guard members may be actuated longitudinally. Connected with the handle and yforming an extension of the same, is a plate having pins entering inclined slots formed in the guard members, whereby as these guard members are moved longitudinally, the pins engaging the said'slots, serve yto throw the guard members inwardly and outwardly as may be desired whereby more or less of. the opposite edges oi' the blade is exposed( Another feature oi' Inyimproved construction, consists in y portion of the rotary nut member-and the adjacent portionloi' the handle, whereby -the adjustment oi' the guards may be conveniently acconviplished. For instance the han-` dle member has a mark on one side of which is the letter 'C to indicateclose and upon the j other side the'letter O to indicate open. The iigureswith which the protruding end member is provided, indicate the degree of rotary movement imparted to the nut and` consequently the degreeof longitudinal ad- Specicatio'n of Letters Patent.

justment'imparted to the guard members. When the user of the razor has once adjusted these guard members to suit, he will always the proper adjustment by imparting `a corresponding degree of movement to the nut.

Having brieiiy struction, I same in detail reference bein made to the accom anying drawing in whic 4is illustrated an emliodiment thereof.

will proceed to describe the.

yThe same reference characters indicate the same parts in all the views.

Let the numeral 5 designate each of the two guard members whose outer edges are toothed as shown at 6.

a stem 8 having adapted to be engaged by a nut 10' swiveled in the outer extremity of the handle 12 by meansof aspring ring 13, which en ages circumferential grooves formed in tie Inner .wall of the handle and the outer wall of the n utl This nut is provided with an extenjslon member 14 which forms a continuation ofthe handle and is of the same size as the These guard members are provided with separated extensions 7 which merge at their outer extremities into a threaded extremity 9 engaging the outer end of lthe handle.

latter, the shoulder or" the nut member 1li lt is evident that by turning the nut 10, which .may be easily accomplished by. the use 'of the milled extension 14, the guard membersl may be moved longitudinally in the handle.

The greater portion ofthe handle is cylindrical in shape. its inner eXtremit 15, however, is somewhat flattened where y its width is increased, to make room for the guard parts 16 which increase in width at the inner extremity of the. handle.' This handle is provided' on one side with an veirtension member 17. This extension member has a reduced part 18 which. entersA the' two studs or short pins 23 which enter counterp art openings formed in the bla de 22. This member 17 is also provided with two pairs of relatively'small pins 24, which engage slots'25 formed in the guard members 5 and inclined to the direction of the length of the guard members. Hence as the guard memers are moved lon 'tudinally or in the direction of the len t of the handle, in the one'direction-Qr lille other, 'these members will be lmoved apart or caused to approach veach other as may be desired depending of `course upon' the direction of movement.

The backing plate 26 en, ages the blade on the opposite side from t' e guard members and is provided at its outer extremity with a hoek 27 which is of suflicient width to slip over the thickness of the blade, the guard members and the handle extension 17, the hook engaging a recess as shown in dotted lines formed in the last named handle meme ber. When the back blade is put in place or moved to thrust the lip 28 into the recess 29 formed on the short handle member 2O the hook 27 is also made to engage the recess formed in the said blade. i

The outer end of the handle is provided with a mark 30 upon one side of which the letter C is formed anden vthe opposite side the letter O. The extension memberla of the nut 10, is provided adjacent the outer extremity of the handle with graduated marks designated 1., 2, 3 and 4 respectively;

it may be assumed .when the member-1 1s in alinementwith the indicating mark 30 ofthe handle member, that the 'guard members are in their normal Aosition. Now if it be desired. to separate t rese guard members for the purpose of concealing morefof the blade,

arrow 0. vVhile if it is desired to close the guard vmembers or bring them nearer together, the nut will be turned in the direction indicated by the arrow C.

,Having thus described my invention, what 'l claim is:

1. A safety razor including a handle and two separated guard members having rcduced separated extensions terminatingr in a stem whose extremity is threaded, and a nut swiveled in the handle vand engaging the threaded portion of the stem, the portion of the handle engaging the guard members being provided with pins and the guard mem'- bers with inclined slots, whereby as the nut is turned the guard members are moved longitudinally in the handle in the one direction or the other for the pur ose of opening or closing tlie same as may e desired, substan tially-as described.-

2, A safety razor, comprising a handle member and a iiat extension, guard members engaging the flat extension ol the handle memlber and lhaving inclined slots engaged by pins with which the liat handle mem er is provided, the guard members having reduced parts protruding into the hollow of the handle and terminating in a threaded extremity, and a nut swiveled in the hollow handle and having a protruding extension for manipulating purposes whereby as the nut is turned, the guard members may be moved. longitudinally of the handle for the purpose of separating them or causing them to approach each other as may be desired.

8. safety razor including a hollow handle memberand an extension member projecting beyond the hollow p'ortion of the handle, separated guard members engaging the extension member, the extension handle member and the guard members being connected by pins and inclined slotswhereby as the guard members are moved longitudinally of the handle they are caused to separate or approach each other, a nut connected in operative relation with the guardl members whereby the latter may be moved longitudinally of the handle, the nut member protruding from the handle and being graduated with reference to an indicating mark -formed on the .handle to designate the degree of movement imparted to the guard members as the nut is rotated, substantially as described.

4. A safety razor comprising a handle have ing a hollow member, a plate connected with the hollow member,v two separated. guard members engaging the plate member, means for ,connecting the plate member and the guard member to cause the guard members to recede and approach each otheras they are moved.' longitudinally upon the plate in the one direction or the other, the guard members being provided with extensions protruding into the hollow handle member, their extremities' being threaded, and a nut having a swiveled connection with the hollow handle member and en aging the threaded extremities of the guard extensions whereby as the nut is turned the guards may be moved longitudinally in either direction upon the said plate member for the purpose set forth.

5. In a razor, the combination of a hollow handle member, an extension plate member connected with the hollow handle member, two i .ard members mounted on the plate mem er and connected therewith to .cause the guard members to recede and approach eachother as the guard members are moved longitudinally thereon in the one direction or the other, the guard members being `proy vided with reduced extensions entering the hollow handle member Iand merging into an integral threaded extremity, and a nut swiveled in the hollow handle member and- In testimony whereof I ailx my signature in presence of two witnesses.
